To Have Or to Be? is a seminal work from the second half of the 20th century. It serves as a manifesto for a new social and psychological revolution aimed at saving our threatened planet. This book encapsulates the penetrating thought of Erich Fromm.

Fromm's thesis explores two modes of existence that battle for the spirit of humankind: the having mode, which focuses on material possessions, power, and aggression, forming the foundation of universal evils like greed, envy, and violence; and the being mode, which is rooted in love, the pleasure of sharing, and productive activity.

This book is a brilliant program for socioeconomic change, urging readers to reflect on their own lives and society.
